Ha-VIS eCon Ethernet Switches HARTING Ha-VIS eCon 2000, 3000, and 4000 Ethernet Switches are unmanaged Plug-and-Play Ethernet switches available in slim (eCon 3000 series), flat (eCon 2000 series), and robust (eCon 4000) metal housings. Ha-VIS eCon 2000 and 3000 switches are available with variants including PoE or PoE+ functionality that increase performance in modules and reduce the overall number of components used in control cabinets and in the field. Ha-VIS eCon Ethernet Switches are designed with up to 16 Fast Ethernet, with up to 8 Full Gigabit ports, and allow for cost-efficient and quick expansion and/or reconstruction of network infrastructures. With an extremely flat design, Ha-VIS eCon 2000 Ethernet Switches are ideal for installations where space is restricted towards the cable connection at the front.
